Struct Domain

pub struct Domain(/* private fields */);

Specification of the communication domain for a socket.

This is a newtype wrapper around an integer which provides a nicer API in addition to an injection point for documentation. Convenience constants such as Domain::IPV4, Domain::IPV6, etc, are provided to avoid reaching into libc for various constants.

This type is freely interconvertible with C’s int type, however, if a raw value needs to be provided.

Implementations

impl Domain

Unix only API.

pub const PACKET: Domain = _

Available on crate feature all and (Android or Fuchsia or Linux) only.

Domain for low-level packet interface, corresponding to AF_PACKET.

pub const VSOCK: Domain = _

Available on crate feature all and (Android or Linux) only.

Domain for low-level VSOCK interface, corresponding to AF_VSOCK.

impl Domain

pub const IPV4: Domain = _

Domain for IPv4 communication, corresponding to AF_INET.

pub const IPV6: Domain = _

Domain for IPv6 communication, corresponding to AF_INET6.

pub const UNIX: Domain = _

Domain for Unix socket communication, corresponding to AF_UNIX.

pub const fn for_address(address: SocketAddr) -> Domain

Returns the correct domain for address.

Trait Implementations

impl Clone for Domain

fn clone(&self) -> Domain

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Domain

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<Domain> for c_int

fn from(d: Domain) -> c_int

Converts to this type from the input type.

impl From<i32> for Domain

fn from(d: c_int) -> Domain

Converts to this type from the input type.

impl PartialEq for Domain

fn eq(&self, other: &Domain) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Domain

impl Eq for Domain

impl StructuralPartialEq for Domain

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
